I’ve observed the incessant complaints on various cancer blogs and discussion boards about BC/BS "denial of coverage" on the backs of injured and diseased human beings during their fight with the great crab.
In one case, the patient was denied a CT scan. As the poster said, "because BC/BS is practicing medicine and deciding that such a thing is not medically necessary." Without the CT scan, there was no way for the doctor to definitively tell if a swollen leg is cancer related or a blood clot. The physician couldn’t make a diagnosis based on the best available technique to make that diagnosis.
Another poster presented the case that BC/BS used to cover Pet Scans. Unfortunately, some study came out stating that Pet Scans aren’t more effective than CT Scans to find colon cancer. With that one study, BC/BS had decided not to cover the Pet Scan, even against the physician protest.
